Appendix A I Extended Screen and Keyboard Control
Keyboard Key Reassignment
ESC [* ; * ;... * p
or ESC [“string” * p
or ESC [* ;“string”; * ; * ;“string”; * p
or any other combination
of strings and decimal numbers
Changes the meaning
of a key on the keyboard. The first ASCII
code in the control sequence defines which code is being mapped.
The remaining numbers define the sequence
of ASCII codes gen-
erated when this key is intercepted. However, if the first code in
the sequence is zero
(NUL), then the first and second codes
make up an extended ASCII redefinition. (See Appendix
B for a
list
of ASCII and extended ASCII codes.)
Examples:
1.
2.
Reassign the Q and q key to the A and a key (and vice
versa):
ESC [65;81p
A becomes Q
ESC [97;113p a becomes q
ESC[81;65p
Q becomes A
ESC [113;97p q becomes a
Reassign the
F1O key to a DIR command followed by a car-
riage return:
ESC [0;68;“dir”;13p
The 0;68 is the extended ASCII code
for the F10 key. 13 decimal
is
a carriage return.
